The material of the dielectric film of described iron core intimate surface laminating is smooth and the sub-film of the good polyurethane of thermal endurance.
In described winding slot, often organize in winding slot and have two adjacent notches, the interval angles between these two adjacent notches is 30 °.
Described positioning unit comprises location hole and linear grooves, described location hole is out the strip hole in iron core surface, the width in this strip hole is equal with the width of rebate of winding slot, and this strip hole and winding slot group are for being crisscross arranged, and adjacent strip span angle is 90 °; Have linear grooves in described bobbin hole, be convenient to bobbin and be accurately placed into rapidly corresponding position in bobbin hole.
Technique effect of the present utility model:
1. have employed soft-magnetic composite material, while minimizing manufacturing process and manufacturing cost, compare the iron core that steel disc is stacking, can also have comparatively high structural strength, not yielding, magnetic property is stablized, also can improve the performance of residing Linearkompressor, reduce the energy loss of place linear electric machine;
2. the quantity of winding slot group is 4 groups, can be convenient to the winding of coil, additionally reduces notch quantity, reduces the cost manufacturing and process;
3. the setting of positioning unit, can improve the installation effectiveness between bobbin in Linearkompressor and iron core.
